RAILROAD-VELOCIPEDE.

Specification of Letters Patent.

Application filed April 28, 1911.

Serial No. 623,837.

, vide a vehicle of the character mentioned with means for applyingpower by both foot and hand, and also to furnish means for amplifying oraugmenting thepower when an additional rider is carried on the vehicle;and to provide a construction ofv propelling levers which coact tomaterially augment the propulsive power applied.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in allthe views, and in whichFigure 1 is a side elevation of a velocipede constructed and arranged inaccordance with the present invention; Fig. 2 is a vertical crosssection taken on the line 22 in Fig. 1; Fig. 3 is a vertical crosssection taken on the line 3.3 in Fig. 1; Fig. 4 is a detail view, inperspective, showing a clamp for holding the cable in operative relationwith a return spring of the intermittent drive; Fig. 5 is a detail Viewin per spective of a coupling clamp for engaging the driving cable withfoot power levers.

As shown in the drawings, and particularly in Fig. 1 thereof, thevelocipede frame is provided with two seats 11. The seats 11 aresurmounted on side bars 12. The side bars 12 are connected with thehounds 13 by means of brackets 14. If it is desired to form an easyriding body the brackets 14 may be constructed from spring material andbent to compress under the weight applied on the side bars 12. Thehounds 13 are provided with bearing boxes .15, which boxes are fixedlysecured to the under side of the said hounds. The axles of the wheels 16are mounted in the boxes 15, one of said axles having fixedly attachedthereto a pinion 17. The wheels 16 are of usual constructionprovided forrolling on railway tracks, and differ from the ordinary wheel in theprovision of the flanges 18 whereby they are retained on and guided bythe railway track A. The pinion 17 is connected by means of atransmission gear wheel 19 Patented Dec. 26, 1911. I

to a crank driven gear wheel 20. The driving power for the velocipede isprimarily imparted to the crank wheel 20. In the accompanying drawingstwo forms of power production and transmission mechanisms are shown.These two mechanisms may be denominated the hand power driving mechanismand the foot power driving mechanism. The hand power driving mechanismis connected to the wheel 20 by means of crank pins 21 and pitman rods22 pivotally connected therewith. The pitman rods 22 are pivotallymounted on pins 23 set out from the sides of two levers 24. The levers24 are pivoted at'25 in foot blocks 26, which blocks are carried instirrup brackets 27. The stirrup brackets 27 of which there are two, aresuspended from each of the hounds 13, as seen best in Fig. 2 of thedrawings. The levers 24 are extended above the foot blocks 26, as bestseen in Fig. 1 of the drawings, and are pivotally connected at 28 tolinks 29. The links 29 are pivotally connected by means of a cross bar30 to the hand levers 31. The hand levers 31 are provided at the upperend with two hand bars 32, which are connected by means of side bars 33with the levers 31, as shown in Figs. 1 and 2 of the drawings. Eachlever 31 is pivoted upon a foot block 34, fixedly mounted on the hounds13, said levers being provided with bearings 35 to fit the pivot pins 36set out from the said blocks 34.

The foot power driving mechanism disclosed in the drawings consistsprimarily in the foot levers 46 and 47. The levers 46 and 47 arepivotally connected to the blocks 54 which are mounted upon the sidebars 12. Each of the levers 46 and 47 is connected by means of a pin 49to an endless cable 43. The cables 43 are each provided with a clamp 48having extended therefrom a bracket 50 perforated to receive the pins49. The cables 43 are reeved upon the pulleys 44 and 45, said pulleysbeing fixedly mounted upon the shafts 38. The shafts 38 are supported inbearings in the braces 56 connecting the side bars 12 and the hounds 13.The cables 43 are each fixedly connected to one of the levers 24 bymeans of a pin 57 as best seen in Fig. 1 of the drawings. A spiralspring 51 is employed by me to maintain the proper tension on the cable43' and to take up any slack which may be produced therein when thevelocipede is used by a simple operator. spring 51 is secured at 49 tothe lever 47.

The operation of a velocipede constructed and arranged as set forth andas shown in the accompanying drawings is as follows: When the velocipedeis driven by one person, that person is seated on the seat 11 faceforward. The rider is within easy grasp of the hand bar 32 nearest hisseat. His feet rest upon the treadles 55 of the lever 46 which isfarthest from the seat 11 occupied by him. With the hand bar and lever31 connected therewith being thrown forward, the operator braces himselffor the pull by pushing against the treadles 55 of the lever 46, pullingat the same time upon the hand bar 32 and the lever 31. By means of theconnecting links 29 the levers 24 are rocked on their pivots 25, forcingthe pitman rods 22 backward to rotate the wheel 20, and therethrough,the wheels 19 and pinion 17. The pinion 17 being rigidly mounted on theshaft of the driving wheel 18 the velocipede is caused to roll in thedirection to which the rotation is imparted. The momentum beingestablished the crank pin 21 is carried over the dead center, and whenthe operator now pushes forward on the hand bar 32 and the lever 31 therotation of the wheel 20 is maintained substantially unbroken. The powertransmitted by the legs through the levers 46 is by means of the cable,43 which is anchored upon the lever 24 by the pin 57.

It will be understood that the levers 46 are only employed as means fordriving the velocipede when and as the hand bar 32 and the lever 31 aredrawn toward the single operator. 7

When two operators are employed the second operator sits on the advanceseat 11 facing toward the rear of the velocipede, and facing likewisethe lever 31 and the hand bars 32 mounted thereon. When grasping thesecond of the hand bars 32, and the one nearest the front seat, thesecond operator rests his feet upon the treadles 55 of the lever 47. Inthis position the two riders cooperate, each alternately pulling uponhis hand bar 32 and at the same time pushing in a bracing manner uponthe foot treadles 55 and upon the levers 46 and 47. In this manner itwill be noted that when there are two riders the cranking operation uponthe wheel 20 is continuously maintained, and that in each movement ofthe lever 31, whether being forced to the front or rear, is employed toeXert the full cranking power upon the pitman rods 22.

The disposition of the various levers and the ratios in the lengthsthereof are relied upon to augment the power applied by hand and foot.In the approved construction I form the lever 31, 30 inches in lengthand arrange the connection with the link 29 on the said lever so that 18inches of the said The length is disposed between the said connectionwith the link and the pin 36. The link.

29 I prefer should be 6 inches in length. The lever 24 is formed 22inches long. The bracket 27 I construct to extend 8 inches below thehounds 13. The pitman rod 22 is connected to the lever 24 at 7 inchesabove the pivot 25. The levers 46 and 47 are 12 inches in length, andthe pivots therefor are raised 2 inches above the side bars 12. I Thecables 43,'to which the said levers 46 and 47 are attached, areconnected to the levers 24 15 inches above the pivot 25. The said cablesare attached to the foot levers about 8 inches below the pintles 53.

The above stated construction and arrangement of the levers will resultin an amplified power when applied by the hands at the crossbars 32 andby the feet at the treadles 55. It will be understood, however, thatwhile I prefer the above arrangement and construction as productive ofwhat appears to me the most economical employment of the force applied,I do not wish to be confined to such construction and arrangementspecifically.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is p 1. A railroad velocipede, comprising ahand lever pivotally mounted in the frame of the velocipede; a powermultiplying lever link-connected with said hand lever and pivotallymounted in the frame of the machine below the mounting of said handlever; a translating mechanism operatively connecting said powermultiplying lever and the driving axle of the velocipede; and aplurality of foot treadles pivotally mounted in the frame of thevelocipede and operatively connected with the said translatingmechanism. 7 g

In a railroad velocipede of the character described, a drivingmechanism comprising a crank wheel; a main rocking lever; a pitmanconnecting said Wheel and said lever; and means for rocking said leverembodying hand operated and foot operated levers each operativelyconnected with said main rocking lever.

3. In a railroad velocipede of the character described, and in thedriving mechanism therefor, a crank wheel; a rocking lever operativelyconnected with said wheel; a 7

ing lever, the points of connection between the said foot lever and saidrocking lever being closer to the mounting of said foot lever than tothe mounting of said rocking lever.

4. In a railroad Velocipede of the character described, and in thedriving mechanism therefor, a main rocking lever piv'otally mounted inthe frame of the velocipede and in a dropped frame provided therefor; ahand operated lever pivotally mounted in the frame of the velocipedeabove the pivotal mounting of said main rocking lever; a link connectingthe upper end of said rocking lever with said hand operated lever at apoint removed from the fulcrum of said hand lever and at a distancetherefrom less than the length of said rocking lever; a plurality ofswinging foot levers flexibly connected to swing in unison; meansconnecting said foot levers with said rocking lever; and a translatingmechanism interposed between the driving Wheel of the velocipede andsaid rocking lever for transmitting a rotary motion to said drivingwheel from said rocking lever.

- In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
